Method and apparatus for multimedia broadcast multicast service
First Claim
1. A method of assigning Multimedia Broadcast Multicast Service (E-MBMS) bearers in at least two Multimedia Broadcast Single Frequency Network (MBSFN) areas in a Third Generation Partnership Project (3GPP) compliant wireless communication system, wherein the 3GPP compliant wireless communication system comprises a radio access network partitioned into a plurality of MBSFN areas, wherein each MBSFN area supports a plurality of E-MBMS bearers for transporting media streams to user equipments (UE), the method comprising:
- receiving, at the application layer of an infrastructure device operably coupled to the 3GPP compliant wireless communication system, information from a UE, the information comprising an identifier that identifies a primary preferred MBSFN area that provides signals to the UE, and an identifier that identifies a secondary preferred MBSFN area that provides signals to the UE;
assigning, at the application layer of the infrastructure device, a first E-MBMS bearer in a first MBSFN area and a second E-MBMS bearer in a second MBSFN area, to support a call to the UE, the first and second E-MBMS bearers providing the same media content to the UE, wherein the first MBSFN area is one of the UE'"'"'s primary preferred MBSFN area and secondary preferred MBSFN area and the second MBSFN area is the other of the UE'"'"'s primary preferred MBSFN area and secondary preferred MBSFN area,wherein the infrastructure device uses the information from the UE in the assignment and transmits the same media content to the UE on each of the first and second E-MBMS bearers.

Abstract
A method and apparatus for assigning Multimedia Broadcast Multicast Service (E-MBMS) bearers in at least two Multimedia Broadcast Single Frequency Network (MBSFN) areas in a 3GPP compliant wireless communication system is provided. An infrastructure device receives identifiers of a primary preferred MBSFN area and a secondary preferred MBSFN area from a User Equipment (UE). The infrastructure device assigns a first E-MBMS bearer in a first MBSFN and a second E-MBMS bearer in a second MBSFN, to support a call to the UE, the first and second E-MBMS bearers providing the same media transmission to the UE as part of a group call. The infrastructure device may receive an attribute parameter comprising a request for Make Before Break service or a request for a boost to coverage, from the UE.

15. A method for a User Equipment (UE) to provide Multimedia Broadcast/Multicast Service (E-MBMS) service area location update information to an infrastructure device in a Third Generation Partnership Project (3GPP) compliant wireless communication system, the 3GPP compliant wireless communication system having a radio access network partitioned into a plurality of Multimedia Broadcast Single Frequency Network (MBSFN) areas, wherein each MBSFN area provides an E-MBMS transmission and supports a plurality of E-MBMS bearers for transporting media content streams to UEs, the method comprising:
-
receiving, by the UE, transmissions from at least two MBSFN areas, each transmission comprising an MBSFN Area Identification (MBSFN Area ID) for a different MBSFN area; choosing, by the UE, a primary preferred MBSFN area and at least one secondary preferred MBSFN area, and notifying the infrastructure device of the 3GPP compliant wireless communication system of the primary preferred MBSFN area and the at least one secondary preferred MBSFN area; and when the UE receives a call provided to a call group comprising the UE, the UE receives the call on at least a first E-MBMS bearer transmitted in a first MBSFN area and a second E-MBMS bearer transmitted in a second MBSFN area, wherein the first MBSFN area is one of the UE'"'"'s primary preferred MBSFN area and at least one secondary preferred MBSFN area and the second MBSFN area is the other of the UE'"'"'s primary preferred MBSFN area and at least one secondary preferred MBSFN area, wherein the first and second E-MBMS bearers provide the same media content to the UE. - View Dependent Claims (16, 17, 18, 19)
